Factors That Impact The Co2 Mitigation Potential Of Cogeneration, Carl Bozzuto

CO2 Summit II: Technologies and Opportunities

Cogeneration systems that produce both heat and power are being promoted as a means of improving the overall energy efficiency around the world, especially in the industrial and power sectors. Claims are often made regarding dramatic improvements in efficiency for such systems. For example, a cogeneration system is advertised as being 85% efficient, while, for example, the U.S. grid is only 31% efficient. However, comparing such efficiency figures directly can be misleading. An 85% efficient cogeneration system is being evaluated at full load and on a first law of thermodynamics basis (i.e., input = output at steady state). The average …

U.S. Doe Carbon Capture Program: Advancing Multiple Generations Of Carbon Capture Solutions Laboratory To Pilot Scale Development, Jose Figueroa

CO2 Summit II: Technologies and Opportunities

The changing energy profile of the United States has reduced energy-related carbon dioxide emissions, according to the DOE Energy Information Administration (EIA). However, this does not preclude the need for carbon capture, utilization and storage (CCUS) as an important solution to climate change. In fact, the change only further supports the need to develop flexible and cost effective carbon capture technologies that can be applied to various fuel sources for power generation application.

CCUS is one of many approaches but is critical to significantly reducing domestic and global CO2 emissions, considering CO2 atmospheric concentrations reached 400 ppm in May 2013 …
